Studies on Antioxidant Activity of Different Solvent Extracts from Fruit of Cnidium monnieri

Objective: To study the antioxidant activities of several extracts of Cnidium monnieri.Method: The methanol,ethyl acetate,methylene chloride and n-hexane extracts were obtained by Soxhlet extraction techniques. The antioxidant activities were studied using 1,1-dipheny-2-picryhydrazyl free radical( DPPH) assay,nitrogen base-double-( 3-ethyl benzene and dihydrogen thiazole moiety-6-sulf onic acid)ammonium salt( ABTS) assay and reducing power assay,and the total phenolic content and the total flavonoid were measured. Result: Different extracts of C. monnieri had better antioxidant activities, and the most outstanding one was found to be the methanol extract. The antioxidant activity of C. monnieri was concerned with the quantity of the total phenolic and the total flavonoid of extracts. Conclusion: The fruit of C. monnieri can be employed as natural antioxidants.
